- Inspect the positive (+) and negative (-) terminals for tightness and corrosion.
- If corroded, use a battery terminal cleaner to clean the connections.
Measure Battery Voltage:
- Connect the multimeter to the battery terminals (red to positive, black to negative).
- If the voltage is below 12.4 volts, proceed to battery replacement.

3. Replace the 12V Battery (if necessary)

Remove Old Battery:
- Disconnect the negative (-) terminal first, followed by the positive (+) terminal.
- Unscrew any retaining brackets and carefully lift the battery out.
Install New Battery:
